The patch looks great, thanks! Care to share your benchmarks as well? A
set of random ASCII text sounds like a reasonable addition to the
microbenchmarks, but I wonder if you also have some profiles from a macro
benchmark or application that shows the effect of this change? And it
would be useful to include non-ASCII in that mix.
